Java 8 Streams: multiple filters vs. complex condition
...le filter invocation using a lambda expression with &&.
But, as said, this kind of overhead will be eliminated by the HotSpot optimizer and is negligible.
In theory, two filters could be easier parallelized than a single filter but that’s only relevant for rather computational intense ta...

Ioc/DI - Why do I have to reference all layers/assemblies in application's entry point?

Yes, that's exactly the situation DI works so hard to avoid :)
With tightly coupled code, each library may only have a few references, but these again have other references, creating a deep graph of dependencies, like this:
Because the dependency graph is deep, it means that mo...
